-LRB- CNN -RRB- -- A Canadian teenage girl has been found guilty of distributing child pornography in connection with `` sexting '' pictures of her boyfriend 's ex-girlfriend , the youth crown prosecutor for Victoria said Friday .

The British Columbia case of the then 16-year-old , who is not identified because she is a minor , is believed to be one of the first cases in Canada where a teenager has been convicted of child pornography charges related to `` sexting . ''

The teenager , who also was convicted of uttering threats , is out on bail while awaiting sentencing , Crown Prosecutor Chandra Fisher said . She declined to speculate on what sentence the teen might face .

Calling the case `` precedent-setting , '' Fisher said the case should serve as a warning to teens about what they text and post online .

The case began in November 2012 when the teen learned that her 17-year-old boyfriend was still in contact with his former girlfriend .

`` The accused was not at all happy that he was still in touch with his ex , '' Fisher told CNN .

The teenager initially threatened the ex-girlfriend on Facebook , the prosecutor said . She then texted five explicit pictures of the ex-girlfriend that she found on her boyfriend 's phone to a group of people , Fisher said .

The teen 's attorney , Christopher Mackie , said the charges were inappropriate .

`` Our sights have always been set on the constitutional question . ... She never denied that she did this , '' he told CNN . `` Online bullying , yes . Child pornography , no . ''
